mesa/get: fix a breakage after rebase

trivial.

i965/vec4: don't copy ATTR into 3src instructions with complex swizzles

The vec4 backend, at the end, does this:

    if (inst->is_3src()) {
       for (int i = 0; i < 3; i++) {
          if (inst->src[i].vstride == BRW_VERTICAL_STRIDE_0)
             assert(brw_is_single_value_swizzle(inst->src[i].swizzle));

So make sure that we use the same conditions when trying to
copy-propagate. UNIFORMs will be converted to vstride 0 in
convert_to_hw_regs, but so will ATTRs when interleaved (as will happen
in a GS with multiple attributes). Since the vstride is not set at
copy-prop time, infer it by inspecting dispatch_mode and reject ATTRs if
they have non-scalar swizzles and are interleaved.

Fixes assertion errors in dolphin-generated geometry shaders (or
misrendering on opt builds) on Sandybridge or on IVB/HSW with
INTEL_DEBUG=nodualobj.

mesa: Fix locking of GLsync objects.

GLsync objects had a race condition when used from multiple threads
(which is the main point of the extension, really); it could be
validated as a sync object at the beginning of the function, and then
deleted by another thread before use, causing crashes. Fix this by
changing all casts from GLsync to struct gl_sync_object to a new
function _mesa_get_and_ref_sync() that validates and increases
the refcount.

In a similar vein, validation itself uses _mesa_set_search(), which
requires synchronization -- it was called without a mutex held, causing
spurious error returns and other issues. Since _mesa_get_and_ref_sync()
now takes the shared context mutex, this problem is also resolved.

Fixes bug #92757, found while developing Nageru, my live video mixer
(due for release at FOSDEM 2016).

st/nine: Introduce STREAMFREQ state

Previous vertex elements code update
was protected by
'if ((group & (NINE_STATE_VDECL | NINE_STATE_VS)) ||
state->changed.stream_freq & ~1)'
itself protected by
'if (group & (NINE_STATE_COMMON | NINE_STATE_VS))'

If no state is changed except the stream frequency,
no update would happen.

This patch solves the problem by adding a new
NINE_STATE_STREAMFREQ state.
Another way would be to add state->changed.stream_freq & ~1
check to the main test.

st/nine: Use ff vertex shader when position_t is used

When an application sets a vertex shader, we are supposed
to use it, and when no vertex shader are set, we are supposed
to revert to fixed function vertex shader.

It seems there is an exception: when the vertex declaration
has a position_t index, we should revert to fixed function
vertex shader.

Up to know we were checking if device->state.vs is set
to know whether to use programmable shader or not.

With this commit we determine whether we use programmable shader
or not when vertex shader/declaration are set, but
stateblocks do complicate things a bit.
